IMPROVEMENT IN TENTS.

Specification forming part of Letters Patent No.. 33,346, dated September 24, 1861i.

To @ZZ whom it may concern: i

Be it known that I, ANDREW L. HASKELL, of Boston, in the county of Suifolk and State of Massachusetts, have invented a new and Improved Folding rlent, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in whichn Figure l is a perspective view of my tent; Fig. 2, a view of the frame upon which it is stretched; Fig. 3, a diagram showing the dimensions of the tent.

My invention is an improvement in circular tents, and has for its object to increase the available space within the tent, and at the same time to'diminish its `height and secure better shelter and ventilation.

To enable others skilled in the art to understand my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A is the central standard,-which is planted rmly in the ground, and to thehead of whichare pivoted the arms l), the eXtreme ends of which are jointed at c to the `under arms d. Thelatterd are pivoted at f to a sleeve E, which slides freely up and down upon the standard A. rlhis sleeve is raised, when the tent is to. be pitched, by the cord g, which is fastened to the standard at c and passes beneath the pulley 7L upon the sleeve and over a pulley m let into the standard near its head. By this means the jointed frame is raised into the position represented in Fig. 2, the cord being belayed to a suitable pin k uponthe sleeve.

Before planting the frame the tent I-I, Figs. l and 3, is placed overit. The bottom edge of the tent is stretched out and secured to the stakes oc and the sleeve E is raised. The ends of the arms b and CZ entering the corners p distend the tent, thereby enlarging the upper portions of the tent and giving greater room for the head. The under bar d may be used to hold knapsacks or other articles for which space upon the ground would otherwise be required, and the cords s, which pass through the bars d, serve to hold clothes or anything which it may be desired to suspend therefrom.

, An opening O, for purposes of ventilation, is made in the ioof of the tent, and is covered by a iiap Pto exclude the rain. For this purpose the iap is drawn down over the holeV by the cords r. (Shown dotted in Fig. l.) It is raised to uncover the opening by means of the cord T, which is attached at t to the lower edge of the iiap. For the purpose of further steadying the tent, guys R are attached at points intermediate between the points p where the tent hangs upon its frame, and are led to stakes 3/ outside of the circle of stakes x.

In Fig. 3 is shown a diagram of the dimensions which I have found to be convenientviz., for a tent of sixteen feet diameter at the base I would have six feet three inches clear height to the inner ends of the arms d and eight feet under their outer ends. From the inner ends of the arms CZ to the head of the pole A should be three feet nine inches, to give a sufficient slope to the top of the tent. In some cases I propose to lengthen,

the under bars CZ a little beyond the point c, so that the upper part of the tent may not rest upon the bars b, but only on the head ofl the standard A and on the ends of the arms d. This is to avoid contact of the canvass with the frame at more points than is necessary, as I find that the rain is more apt to penetrate the canvas wherever it rests upon the frame. 'Vhen the tent is to be struck, the cord g is cast off from its fastening and the sleeve E is lowered down on the standard A, the bars CZ and b closing up close to the standard, when the whole frame may be rolled up in Ithe tent I-I for transportation.

I am aware that S. M. Davis has been granted a patent fora folding adjustable tent, bearing date of July 23,1861, and of which patent I am now the sole owner1- as assignee; but its construction admits of the rain beating in at the top, the center pole, capped by the pulley, extending through the top. The more effectually to secure the best shelter, the apex of my tent is closed and fastened by a button in the top of the center pole, and I place the pulley apparatus between the two sets of jointed arms and have a Ventilator on the slope of the top, which I can regulate at pleasure by means of cords.

What I claim, and desire to secure as my invention by Letters Patent, s-

- The arrangement of the pulley in the eenter pole, as described, for the purpose of raising and lo\\fering the tent, the same be ing constructed and operated substantially as set forth.A
